Question

why do we feel cool after applying shave lotion or perfume

Answer 1

We feel cool after applying shave lotion or perfume, because -

• Most of the shave lotions and perfumes,contain alcohol as one of the main ingredients.

• Now,when this alcohol gets into contact with our warm skin,it evaporates at a very fast rate.

• This fast evaporation causes a significant amount of latent heat transfer from our skin to the alcohol.

• This transfer of latent heat, creates a cold feeling on our skin.

Answer 2

Answer:

Shave lotion and perfume contain little amount of spirit. When we apply them to our skin, the spirit in them will evaporate by absorbing the heat in our body. As we lose heat we feel cool. This is the reason why we feel cool after applying shaving lotion or perfume.
